Abstract

A polishing head comprises a casing with abrasive segments attached thereto made to oscillate on radial shafts driven by a ring with vertical eccentric rotary motion. The ring is coupled to a first eccentric and to a crown gear is fixed to the casing while a pinion is coupled with rotational motion to a second eccentric connected to the structure of the machine. A plurality of pins are mounted on eccentric planetary gears coupled with rotational motion to the ring and to the body of the head with a further pair of crown and pinion gears provided in which the first crown gear is rigidly connected to a second pinion and rotates with it on the second eccentric. The first pinion is rigidly connected to the said first eccentric, concentrically with the axis of the head and the second crown gear is rigidly connected to the housing of the polishing head concentrically with the axis of the head.
